Marathon Water Heater Pricing

On April 16, 2015, new National Appliance Energy Conservation Act (NAECA) efficiency standards, which impact water heaters, were mandated. Water heater manufacturers are now unable to build any water heaters with a capacity greater than 50 gallons. As a result, La Plata Electric will only inventory and have available for sale, 30, 40 and 50-gallon Marathon water heaters from this date forward.

The last water heater you’ll ever own. Marathon water heaters are warrantied for life and built to last for as long as you own your home. While a traditional steel tank will erode and potentially rust over time, Marathon water heaters are manufactured with polybutene which is impervious to rust and corrosion, and is one of the many reasons why this water heater may be the last one you’ll ever need to buy.
